1. API Description

Domain name for API request: clb.tencentcloudapi.com.

This API is used to modify the forwarding weights of real servers bound to a CLB listener in batches. It supports layer-4 and layer-7 CLB listeners but not Classic CLB.
This is an async API. After it is returned successfully, you can call the DescribeTaskStatus API with the returned RequestID as an input parameter to check whether this task is successful.

A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: clb.ap-shanghai-fsi.tencentcloudapi.com

4. Example

Example1 Modifying real server weights in batches

This example shows you how to modify the weight of the real server ins-19404pl5 (port 110) bound to the forwarding rule loc-o8cnyw6c under the listener lbl-4b5hnc9a in the CLB instance lb-dx98lwo0 to 50, and modify the weight of the real server ins-19411tzv (port 80) bound to the forwarding rule loc-8c5pdrb8 under the listener lbl-20jjtaaw to 30.

Input Example

https://clb.tencentcloudapi.com/?Action=BatchModifyTargetWeight
&LoadBalancerId=lb-dx98lwo0
&ModifyList.0.ListenerId=lbl-4b5hnc9a
&ModifyList.0.LocationId=loc-o8cnyw6c
&ModifyList.0.Targets.0.InstanceId=ins-19404pl5
&ModifyList.0.Targets.0.Port=110
&ModifyList.0.Targets.0.Weight=50
&ModifyList.1.ListenerId=lbl-20jjtaaw
&ModifyList.1.LocationId=loc-8c5pdrb8
&ModifyList.1.Targets.0.InstanceId=ins-19411tzv
&ModifyList.1.Targets.0.Port=80
&ModifyList.1.Targets.0.Weight=30
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "83329908-a282-4f9f-8ab-031a3025b377"
  }
}

Example2 Batch modifying the weights of servers bound to layer-4 and layer-7 listeners

This example shows you how to modify the weights of servers for the layer-4 and layer-7 listeners under a CLB instance at the same time.

Input Example

https://clb.tencentcloudapi.com/?Action=BatchModifyTargetWeight
&LoadBalancerId=lb-1kkno9qf
&ModifyList.0.ListenerId=lbl-mhtffs09
&ModifyList.0.Targets.0.InstanceId=ins-kjp6cb2f
&ModifyList.0.Targets.0.Port=79
&ModifyList.0.Targets.0.Weight=50
&ModifyList.1.ListenerId=lbl-661zpn3b
&ModifyList.1.LocationId=loc-78p1r0vb
&ModifyList.1.Targets.0.EniIp=10.202.0.96
&ModifyList.1.Targets.0.Port=123
&ModifyList.1.Targets.0.Weight=30
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "38bab2ce-616d-412c-a4b0-36110d5b17a3"
  }
}
